| Abstract: | It is the basic method of understanding the performance behavior of big diameter driven cast-in-place pile by the test of stress and strain. Based on an actual case with the method of static test, and by analyzing the pile's curve of Q-S, curve of axial force, curve of unit frictional resistance stress and the variable curve of the frictional resistance stress followed with time, the authors got some useful conclusion which can be help in the design and construction of the similar engineering. |
